Publication number: 20130303896Abstract: A system can include an implantable device, an instrument, a display device and a processor. The implantable device can include a port and a localizer for generating a navigation field. The instrument can include a tracking device for sensing the navigation field. The processor can be operably coupled to the tracking and display devices and operable to determine a real-time location of the instrument relative to the port and a trajectory of the instrument relative to an insertion axis of the port. The processor system can be operable to cause the display device to graphically render the instrument as a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory and in spaced relation to each other along the axis. A first ring of the plurality of rings can be positioned at the determined instrument location relative to a graphical representation of the port location.Type: ApplicationFiled: July 8, 2013Publication date: November 14, 2013Inventors: Scott L. KALPIN, Andrew BZOSTEK, Steven L. HARTMANN, Matthew W. KOENIG, Brad JACOBSEN, Scott A. SARKINEN, Peter J. BOROWITZ, Bradley A. JASCOB

Publication number: 20130296830Abstract: A support tool for a supply assembly delivers a functional fluid to an implantable medical device. The supply assembly defines a supply axis. The support tool includes a support member defining an opening. The opening has a support axis, and the opening is configured to receive the supply assembly. The support member includes a three dimensionally contoured nesting surface that conforms to a corresponding three dimensionally contoured surface of the supply assembly. The corresponding surface of the supply assembly nests against the nesting surface to support the supply assembly such that the supply axis remains substantially fixed relative to and aligned with the support axis.Type: ApplicationFiled: July 1, 2013Publication date: November 7, 2013Inventors: Scott L.

Publication number: 20120283639Abstract: A medical device system comprises a reservoir configured to store a therapeutic fluid and a medical pump configured to deliver the therapeutic fluid from the reservoir to a patient. The system also comprises a sensor that can detect a characteristic associated with the pump and a processor to determine if the characteristic detected indicates the reservoir is empty or near empty. The characteristic may comprise a characteristic of a noise made by an actuator within the pump at the end of a pump stroke.Type: ApplicationFiled: July 19, 2012Publication date: November 8, 2012Applicant: Medtronic, Inc.Inventors: Irfan Z.

Publication number: 20120277716Abstract: A total dose of a therapeutic agent to be delivered to a patient by an infusion device over a total period of time is automatically divided into a plurality of unit doses to be delivered to the patient over a plurality of unit periods of time. The infusion device is automatically programmed to deliver one of the unit doses of the therapeutic agent to the patient over its respective unit period of time, after which the one unit dose is delivered, and a determination is made of whether an error occurred in delivering the one unit dose to the patient. Delivery of the total dose of the therapeutic agent to the patient may include iteratively automatically programming the infusion device to deliver successive unit doses upon determining that no error occurred in delivering a previous unit dose to the patient. Accordingly, the risk of improperly dosing the patient with the therapeutic agent in an event of a software or hardware anomaly within the infusion device is prevented or reduced.Type: ApplicationFiled: April 28, 2011Publication date: November 1, 2012Applicant: Medtronic, Inc.Inventors: Irfan Z.

Patent number: 8192398Abstract: Systems and methods for orienting a medical instrument relative to at least a portion of a medical device include a first tilt detector associated with the medical instrument and a second tilt detector associated with the medical device. The first tilt detector may be within an orientation device that is coupled to or separate from the medical instrument. The tilt detectors generate signals that may be used to determine the relative orientation between at least a portion of the medical device and medical instrument. For example, in some embodiments, the signals may be used to determine whether the orientations of the portion of the medical device and the medical instrument substantially match.Type: GrantFiled: March 13, 2008Date of Patent: June 5, 2012Assignee: Medtronic, Inc.Inventors: Jason J.
